Novel pseudodisaccharide-type aminocyclitol antibiotic models, built up from D-arabinose, D-ribose, D-glucosamine, L-ristosamine and L-acosamine have been synthesized by the glycosylation of. suitably protected (azido)deoxyinosose aglycones derived by the Ferrier carbocyclic ring transformation of carbohydrate precursors. An alternative approach to related pseudodisaccharides, based on the Ferrier carbocyclization of reducing disaccharides, has also been elaborated. This latter method extends the scope of the Ferrier reaction, by demonstrating that acid-labile 2-deoxydisaccharides can also be readily transformed into the corresponding pseudodisaccharides under the slightly acidic conditions of this ring-transformation.

Application of the Ferrier's carbocyclic ring closure to methyl 3-azido-2,3,6-trideoxyhex-5-enopyranosides leads to cyclitol derivatives (3)and (5) suitable for the convenient synthesis of 1,3-diaminocyclitol -type aminoglycoside antibiotic analogues.

The synthesis, chemical derivatization, and investigation of the inhibitory properties of novel cyclitol derivatives on the phosphatidylinositol 4-kinase enzymes PI4K55 and PI4K230 involved in the phosphatidylinositol cycle are reported. Some of the prepared cyclitol derivatives (i.e. 9, 11, 12, and 14) proved to be very powerful and specific irreversible inhibitors of PI4K230 at or below a concentration of 1 mM.

Abstract The mercury salt-mediated carbocyclic ring-transformationreaction of the 3-azido ( 4 ), 3-benzamido ( 8 ), and 3-trifluoroacetamido ( 11 ) derivatives of methyl 4- O -benzoyl-2,3,6-trideoxy-β- d - erythro -hex-5-enopyranoside, methyl 3-azido-4- O -benzoyl-2,3,6-trideoxy-α- d - threo -hex-5-enopyranoside ( 16 ), and its 3- O -benzoyl-β- ( 14 ) and 3-deoxy-α ( 18 ) analogues has been investigated
